This section describes installing and replacing CompactFlash (CF) memory cards in Cisco 1941 integrated services routers. You can perform these procedures when the router has been installed in its working location with all power and interface cables connected. This chapter contains the following sections:

• Preventing Electrostatic Discharge Damage, page 21

• Removing a CompactFlash Memory Card, page 21

• Installing a CompactFlash Memory Card, page 23

Preventing Electrostatic Discharge Damage

Modules Internal to the Cisco 1941 Router

This section describes installing and replacing CompactFlash (CF) memory cards in Cisco 1900 series integrated services routers. It contains the following sections:

To prevent ESD damage, follow these guidelines:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

• Place a removed CompactFlash memory card on an antistatic surface or in a static shielding bag. If

the card will be returned to the factory, immediately place it in a static shielding bag.

• Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages

on the body only; ESD voltages on clothing can still cause damage.

• Do not remove the wrist strap until the installation is complete.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be

between 1 and 10 megohms (Mohms).

Removing a CompactFlash Memory Card

To remove a CompactFlash memory card from the chassis, perform the following steps:

Caution Do not remove a CompactFlash memory card from the chassis while it is being accessed. The CF LED

blinks to indicate when flash memory is being accessed. Removing the CompactFlash memory card from the router while flash memory is being accessed can cause data corruption and erratic operation.

Step 1 Remove the CompactFlash cover by placing a flat screwdriver in the slot and pushing sideways against

the tension to release the cover door. (See Figure 19 and Figure 20.)
